IMPROVEMENT IN REFRIGERATORS.

Specification forming part of Letters Patent No. 143,607, dated October 14, 1873 application filed Juno 28, i873.

To all whom it may concern:

Be it known that` I, WILLIAM M. BAKER, of .Fortville, in the coimty of Hancock and State of Indiana, have invented a new and Improved Refrigerator, of which the following is aspecication:

l In the accompanying drawing, Figure l represents a vertical longitudinal section of my improved refrigerator on the line c c, Fig. 2; Fig. 2, a verticaltransvese section of the same on the line x az, Fig. l; andV Fig. 3, a plan view, showing arrangement of cold-air chamber.

Similar letters of reference indicate corresponding parts.

The object of my invention is to construct the refrigerator in such a manner that, besides simplicity and cheapness, economy ,in the use' of ice, large cooling and condensing surfaces, and a dry cool air for ventilation are obtained. My invention relates to certain improvements upon the refrigerators patented by me December 24, 1872, and May 6, 1873, andV consists mainly in providing, by a compact arrangement of the ice-chamber, in combination with the cold water and air chambers, a larger space for the Vprovision-chambers, and a complete and uniform ventilation of the same.

In the drawing, A represents the outer frame or casing of the refrigerator, constructed in the usual manner. The body of the refrigerator is divided into three main partsthe central provision-chamber B and the two symmetrically-arranged side chambers C. The central chamber B is separated from the side chambers C by cold-water chambers D, which extend nearly from top to bottom along the same.V The Goldwater chambers D are con structed of lsuitable material and width, and

connect with the ice-chambers E, which form the upper part of the side chambers G. The

p melted ice-water, after passing through filter H, which extends laterally in the rear of each side chamber C, with the same width and height, serves to connect the cold-air chamberG with the side and central provision chambers, and produces the ventilation of fresh cold air through the same. To secure the perfect cooling of the air when passing through the air-chamber G, the same is divided by vertical partitions d, which are provided at alternate ends with openings, so that the air takes a more circuitous route. The outer air is introduced to chamber G by aperture e, passes along the partitions d, as indicated by arrows in Fig. 3, and is thoroughly cooled by the ice-water, which passes around it from the ice-chamber E. The cold air passes then through aperture e of air-chamber G into connecting part H, and, by apertures f, into side provision-chamber B'. The apertures f are arranged inthe lower part of provisionchamber B. Tubular openings g conduct the air from the side provision-chamber B', through the cold-water chamber D, into the central' part B, and upward through the same, by the top aperture h, to the outside, as indicated by the arrows in Figs. l and 2.

rEhe advantages of this arrangement of the diiferent chambers are obvious, as the chambers for collecting the ice-water take up a minimum of space and utilize the ice-water, so

that additional provision-chambers are gained,

which are thoroughly and efficiently cooled and ventilated by forcing the cold air through the refrigerator in the manner described.

H aving thus described my invention, I claim as new and desire to secure by Letters Patentl. The cold-water chamber D, having aperture a for the ice-water, and tubular passages g for Ventilating provision-chamber B, as set forth.

2. The cold-air chamber G, having partitions d to produce perfect cooling of air, as described.

3. The combination of frame A, central provision-chamber B, cold-water chambers D, icechambers E, cold-air chambers G, air-spaces H, and side provision-chambers B', arranged and connected substantially as and for the purpose described.
